Supplying high-strength electrodes, submerged arc wires, and flux combinations for pressure vessels, cranes, and heavy structural assemblies.
Thick steel sections ranging from 25mm to over 100mm require consumables that offer deep penetration, flat wetting bead profiles, and extremely low hydrogen levels to eliminate delayed cold cracking.
Magnarc heavy fabrication consumables include high-recovery iron powder electrodes (E7024), radiographic basic low-hydrogen rods (E7018), and Submerged Arc Welding (SAW) wires paired with agglomerated fluxes for multi-wire mechanized welding.
Consumables engineered for heavy section welds, high-speed multi-pass joints, and radiographic pressure standards.
